Here's the answer from RingoM, in the Daz Carrara forum.
*"Go into the Extensions folder and delete these files:
"PoserImporter.dat
"PoserImporter.mcx
"PoserImporter.txt
"PoserImporterFR.txt
"Now PZ3 files will load fine via Poser native import but not the ones that use dynamic hair or "dynamic clothing as those require Transposer

I hope it's only a bug, imports from Daz studio works very  well ...
From my point of view transposer is still better than native import ( wich handles FBmorphs sometimes strangely)
